Id say that your estimate is statistically invalid. Presumably such videos are mainly shared because they feature idiots. Anecdotally, most cyclists I encounter in the wild respect the rules, but the idiots who don't make a stronger impression.
I hate to say it but the situation in London is out of control and I just fear the worst tbh, in that we will get some horrible draconian legislation because of it..
All it takes is a few serious injuries of deaths of people using the crossings.
It's sad as the growth in cycling in London, especially since the pandemic, has been something to behold.
